how to use nexus mod manager with starbound

Then, delete the universe folder in the storage folder, open up the pre-FU backup, and put that universe folder in the storage folder. Now, when it's time to uninstall, back up that storage folder again, this time naming the folder to show that it's the post-FU version of your files. Back that folder up in a folder named 'Pre-FU' or something like that before installing FU. There should be a folder in there called storage.

Your Starbound folder, on Windows, will be under C:/Program Files(x86)/Steam/steamapps/common/Starbound. This is only necessary, btw, because the universe files are shared across all characters. But you don't want to have to wipe everything, do you? You can make a backup of your entire storage folder, pre- and post-FU or another universe-altering mod. You'll probably want to return to at least semi-vanilla sometime, like I did when 1.2 rolled out. Now, let's say you want to go all the way and install Frackin' Universe, a huge mod that alters the universe, adding new planet types, two extra tiers of planets, new stars, new status effects, and even has a new item progression system. Well, unless you mash a bunch of them together, anyway. Perfectly Generic Items don't make very good armor. If it's the armor that's modded, it would be a good idea to make a new set, unless you want monsters to completely annihilate you. Unless you have vanilla armor underneath, anyway. Oh, and change your clothing to vanilla clothing unless you want a naked character. Dismiss any mod-race crew members and evict all mod-race tenants before you uninstall race mods. What you want to watch it with is races, as characters you created with that race will vanish, and any NPCs of that race that you encounter, such as by revisiting a planet with said NPCs, will cause you to crash. I haven't seen what happens with modded blocks, but modded colors will stay (like blocks colored with the Color Wheel mod or character colors added by the Colorbound series), modded items will become Perfectly Generic Items, modded furniture will vanish if it was placed, and modded techs will be replaced by the default tech for that slot.

Uninstalling most other mods is quite safe.
